Hello Chris,
I finally got a response from TNR (Art & Fred), the US Takahashi dealer.
"I don't know which grease Takahashi uses. I tried different greases and
came up with a very thin, very light damping grease.
NYE makes NYOGEL #774VL [very light] and
PG-1S grease [super light]

The 774 series consists of silica thickened synthetic hydrocarbon of various viscosities depending upon how much mechanical dampening is required of various components. The damping greases also provide good water resistance.
So you have two choices to start with, Superlube or Nyogel. If you go the Superlube don't use the spray on version..just my 2 cents worth.
